Roll formed metal trim is an inexpensive material that has a variety of surprising benefits. Most metal trim is inflexible and stiff, but there are a few alloys that help improve the flexibility of metal trim. Aluminum and other lightweight metal mixtures offer strength and flexibility at the same time. Rather than the limited use on right angled objects, flexible trim can be used in a variety of other applications. Three benefits of using roll formed trim include:
Fewer cracks and bends from stress: Non roll-formed trim is inflexible and tends to bend and crack. This happens at once or after a few months of use. Roll-formed trim eliminates this issue from the trim altogether and allows for greater application.
Increased applications and use: There are many applications for roll-formed trim. The trim can be used around corners, on rounded objects, and even on vehicle frames. There are many applications for the trim, and it is easy to use inexpensive flexible trim in place of more expensive trim options without sacrificing on quality or appearance.
Ease of use: Roll-formed metal trim is easier to install than rigid trim. Pieces do not have to be aligned as carefully, which leads to faster installation times and less waste due to broken trim pieces and other imperfections.
These benefits are useful for a wide range of industries and applications from the automotive industry to the construction industry and everything in between.
Metal trim is designed in varying shapes, thicknesses, compositions, colors and to varying standards of functionality and aesthetic appeal; the range of possibilities is very wide. In industrial settings, metal trim is rarely designed to heighten visual appeal, but it is expected to protect edges from multiple impacts without becoming damaged itself. Outside of industrial settings, for products like portable USB memory drives, many of which can feature decorative metal trim, functionality is less important than visual appeal. Because there exists such a range of metal trim varieties, an equally wide range of fabrication processes exists that allow for their creation.The simplest method of metal trim production is roll forming. Complicated or irregular pieces of trim can be produced in many other ways, but for the creation of uniform, simple metal trim, roll forming is likely the most efficient and cost-effective method. The roll forming process requires a roll former, which is a machine that contains a long series of rollers and a cutting system. The roll forming process begins with a stock of metal strip, which can be aluminum, steel or any other metal product suitable for a trim application. The stock may be coiled or it can be in any other shape that allows for easy access to a steady stream of the product. That product is fed into the first rollers, which fit tightly around the contours of the strip. Those rollers direct the strip to the second rollers in the series whose configuration is slightly different than the first rollers. This continues until the end of the series, at which point the rollers are configured in a shape that resembles the intended shape of the metal trim. The metal strip takes that shape and emerges from the roll former as uniform metal trim. It can then be cut and prepared for shipment.
